    Hello,

    one client has a user with an EFS encrypted file.

    There is no DRA on the file.

    The user account and computer accounts have been migrated to another domain.

    Is it possible to retrieve the encrypted file ?

    I dont have actually the certificate but the computer has not been reinstalled, just migrated to a new domain (like the user). Is it possible to retrieve the user certificate when the user has been migrated from DomA to DomB ?

    Can I open a session with RunAs with the old domain credentials to try to export the certificate ?

    Thanks

    If the user profile is still untouched in that machine and there is a trust between the domains, you might be able to activate it by logging in using the old domain account.

    It is possible to migrate the user profile together with the user object using USMT or similar tools.
